/* water_level_chart.css - chart chrome and color tokens for water_level_chart.js * (the Cernavodă water-level chart). * * Light tokens are the default (the page is light). The dark set is selected, not * auto-flipped: it applies when the document root carries data-theme="dark" * (), so a dark card never appears inside a light page. * Series colour: categorical slot 1 (blue, #2a78d6 light / #3987e5 dark), validated * with the dataviz palette checks against both surfaces. * Zoom chrome (selection band, navigator strip, header controls) reuses the same * tokens so it stays quieter than the data. */ .water-level-chart { --chart-surface: #fcfcfb;
